This is the innovative series of Heat Pumps, featuring A CLASS energy efficiency, dedicated to hot water production up to 60 °C and operation up to -20 °C external air temperature, with Scroll compressors, axial fans and integrated hydronic kit. The unit, designed to originate and control – throughout the year – the best comfort conditions in rooms with a high rate of daily attendance, such as enclosed areas destined to the activities of the service sector, autonomously handles winter heating, summer air conditioning and the production of high temperature sanitary hot water. The series, designed with an extremely compact structure for simple installation operations, uses only the electric energy and the heat accumulated in the air, to transfer heat to the rooms, thus allowing considerable energy savings, a high rate of reliability and the shortest start-up times. Flexibility is the main feature of the series, which is indeed combined with terminal units and managed by the innovative, intelligent AQUALOGIK control and optimization system. This makes the use of an inertial tank unnecessary and it guarantees performances with elevated energy efficiency and silent functioning.
The units are compliant to the ErP Regulation.
